Fritsch Analysette 12 DynaSizer laser particle sizer

The Fritsch Analysette 12 DynaSizer laser particle sizer uses a dynamic light scattering technique to enable the measurement of particle size distributions between 1 and 6000 nm. It also has a wide concentration range of 0.0003% to 40 wt%.

When measuring particles only small sample volumes of <50 µL are necessary - these particles are applied directly to the optical measuring cell inside the instrument, therefore making disposables such as cuvettes obsolete.

When measuring the thickness of a sample the strength of the measurement layer can be variably adjusted. This enables the measurement of very thin layers and prevents unwanted multiscattering effects. It also facilitates the measurement of highly concentrated suspensions as well as in opaque media.

The power of the laser can be adjusted to enable the measurement of very dark samples or high particle concentrations of up to 40 wt%.
